It was OK. There were some truly funny and brilliant moments, but as usual with QT, I had trouble sinking into the story because QT always makes you painfully aware that you are watching a movie. He never allows the viewer to just lose themselves in the story because he wants you to remember he's making conscious choices that are oh so artsy and symbolic. His clever nods to other movies and pop culture are never subtle or smooth. I just wish he would allow the story to unfold once without waving to us and pointing "you see what I did there?" It's so fukking annoying. But he is more restrained here than he usually is.
Anyway, Leo and Brad really acted their asses off, and I enjoyed the humor for the most part. I understand what people are saying about the pacing, but that actually wasn't a problem for me. It did feel like Hollywood itself, the personalities, the era was a character in itself, and I think that's what the first hour was about. I did hate the random narrator that pops in a few times in the beginning and then suddenly takes over the last half hour. That was just weird and took me right out of the movie. The ending actually surprised me. I don't know why I thought QT would stick to history, I should have known better. I have mixed feelings about what he did there, but I have to give to him that at least he kept it interesting.
7 out of 10 because QT was still showing his ass, but I enjoyed Leo and Brad.
